hello everyone,

I'm trying to get the rpm from a windgauge. I installed the program example zEn23_01_FMx50. 

When I look at the output values the ACT_CNTV is counting up but the LATCH_LOAD is staying at 0.

How can I get a output of the LATCH_LOAD? What am I doing wrong?

I'm using a S7-312 CPU, a FM350-1 counter and the windgauge has 6 ppr. 

 Thanks

Hello,

Are you using Latch input?

See the manual:

FM 350-1 Counter Function Module Installation and Parameter Assignment

See page 127 etc.

Hi,

Thanks for your answer. The Latch Input didn't work for me but I think this is my fault.

I'm having trouble to get the module correctly working in my software program.

I am using the example program zEn23_01_FMx50, downloaded this to my plc and connected the windgauge to the FM350 module. 

Can someone help me please with adapting the program so that it will give me the rpm of the windgauge?

I've been trying this for several days now and I don't know what to do now.

Thanks,

Jamin
